Although the global economy is still not fully recovered, there have been signs of improvement since the start of this year. The U.S. GDP grew 2.5% in the first quarter of 2013. Even though the growth was slower-than-anticipated, it was significantly better than the growth seen in the final quarter of 2012. China, the world?s second largest economy, has also shown signs of improvement. In Europe, policymakers are under pressure to implement measures to kick start growth. All these developments should boost demand for industrial goods. The industrial sector was among the major gainers in the S&P 500 on Tuesday.
